SPECIFICATION forming part. of Letters Patent No. 316,529, dated April28, 1885.

Application filed November 26, 1883. (Model) To aZZ whom it may concernBeit known that I, LI'JON O. DION, of N atick, in the county ofMiddlesex and State of Massachusetts, have invented a certain new anduseful Device for Opening and Closing Blinds and Shutters, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

My invention relates to devices for operating shutters or blinds fromthe interior of the house to which they are attached; and it consists incertain novel features and arrangements of parts, which will be readilyunderstood by reference to the description of the drawings and theclaims to be hereinafter given.

In the drawings, Figure 1 represents a perspective view of a window theblinds of which are provided with and operated by my improved device.Fig. 2 represents an enlarged side elevation of my improved device, thedifferent parts of which being shown in the positions they occupy whenthe blinds-are closed. Fig. 3 represents afront elevation of the same.Fig. 4 represents a side elevation of the same with the parts thereof inthe positions they occupy when the blind is opened. Fig. 5 represents apartial sectional elevation on line 00 w on Fig. 2. Fig. 6 represents acentral longitudinal section of the rotary lifter. Fig. 7 represents asectional elevation of the blindfastener, the cutting-plane beingtransverse to the window-sill; and Figs. 8 and 9 represent,respectively, a side elevation and a plan of the pintle, which isattached to the blind.

A is a window-frame of the usual construction, B is the sill thereof,and O C are blinds secured thereto by the hinges a a. Each blind isprovided on its lower end with a suitable fastening device for retainingthe blind either in an open or closed position.

The device shown in the drawings consists of avertically-movinglatch, b,secured by one end to the blind near its pivotal edge, while itsopposite end extends through the stapleguide a, and is retained in thebottom thereof by virtue of its own tension. This latch 22, when theblinds are closed, engages with the catch d and retains the blinds inthat position, while it effects the same object when open by engagingwith the catch 6.

A little above the lower hinges a a suitable holes are bored through thewindow-frame, to each of which holes is fitted a metal tube, D, in whichis mounted the shaft E, to the inder end of whichi. 6., that end whichenters the interior of the house-is firmly secured the crank-handle F.Near the outer end of the shaft E the rotary lifter G is firmly securedthereto, so as to revolve therewith. The extreme outer end of the shaftE consists of an enlarged hub, f, to which is firmly secured the spiralspring H, the opposite end of which is secured to the vertical hub g ofthe removable pintle I, mounted in a suitable bearing in the ear J ofthe metallic bracket K, firmly secured by screws or otherwiseto theblind O, the said pintle I being provided with an ear, m, in which isformed an angular notchun, to fit the corner of the bracket K, as shownin Figs. 3, 8, and 9.

WVhen the reduced end of the pintle I is in the bearing in the ear J,and the corner of the bracket K is within the notch n, and the spring His holding the said pintlel in this position, the said pintle is asrigid with the bracket K as if it formed an integral part thereof, andtherefore the blind C may be readily moved about its hinges by rotatingthe pintlel.

' The rotarylifter Gis made of such a diameter that the toe h, mountedon its outer edge parallel to its axis, projects beneath the shoulder '5of the bracket K, the blind being pro vided with a suitable cavity, It,to accommodate such rotation of the toe h. The bracket jecting arm Z, bywhich the blind may be lifted when the said blind is in an openposition.

The operation of my invention is as follows: The different parts of myimproved device being in their normal positions, as shown in Figs. 1, 2,3, 5, and 7 of the drawings, if the blinds are desired to be opened, thehandleF is moved iuthe directionof the arrow, Fig. 1, thereby rotatingthe lifter G and bringing the toe h thereof in conjunction with theshoulder t upon the blind, when, if the lifter G continues to berotated, the blind G will be lifted upon its hinges a a a sufficientdistance to disengage the latch 72 from the catch d. While the blind Ois being thus lifted and the shaftE rotated, the vertical pintle I isprevented from 5 K has extended from its front surface the prorevolvinguntil the latch b is released from the catch'd on account of theengagement of the notch n of the ear m thereof with thecornerofthebracketKupon theblind O,and,there- 5 fore, as one end of thespring is being rotated with the shank E while the other is securelyheld 'in' a fixed position, an extra torsional strain is given to thespring H, which, when the blind G has been lifted so as to disengage thelatch b from the catch d, causes the blind to swing outwardly. Thecontinued rotation of the handle F, shaft E, and hub f causes atorsional strain to be transmitted through the spring H to the pintle I,which. is thereby r 5 cause to rotate in its bearing, and by virtue ofthe notch n-of the ear m, acting upon the corner of the blind O, thesaid blind is also caused to rotate until the latch b engages with thecatch e, when the blind will be retained in an open position.

repeated, with the exception that the toe it acts upon the projectionZto lift the blind, instead of acting upon the shoulder i.

If at any time it is desirable to remove the blind, it can readily beaccomplished by simply go removing the pintle Ifrom its bearing, whichwill sever all connections between that part of the device which is,attached to the frame and that which is applied to the blind, so thatthe blind may be lifted from its hinges.

It is obvious that the connections may be as readily made again bysimply placing the notched end of the ear m against the corner of thebracket K and inserting the reduced end of said pintle I in its bearing.

5 with any other means for rotating the blindas, for instance, a pair ofbevel-gears or a balland-socket joint. Y

. To operate the shutters from the interior of the hous'ein stormyweather without the necessity of opening the window has long been deemedadvantageous, and therefore many attempts have been made to accomplishthis object, the results of which have failed to come into general useeither on account of their liability of getting broken orotherwiseinoperative, or on account of their complexity and cost.

To obviate these difficulties is'the object of this invention. 1

One of the greatestdisadvantages-to be It is obvious that instead of aspiral spring found with devices for this purpose heretofore constructedis that. their only point of fasteningis on the hinged side of the blindand generally in a line with the axis of rotation of the blind, so thatthe wind in rough weather is liable to get so great a leverage upon theblind as to tear it from its points of attachment; but in the improveddevice herein described this disadvantage is entirely obviated, as eachblind has a fastening device secured thereto at some little distancefrom the axis of rotation of the blind, the said fastening device beingoperated, as has already been described, from the interior of the house.I am aware that a coiled spring has been heretofore used fortransmitting power.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is=- 1. A device for operating blinds or shutters,consisting of a shaft adapted to pass horizontally from the exterior tothe interior of the window-frame and provided on its inner end withmeans for rotating it, a support or car adapted to be attached to theblind, and flexible coupling composed of a spiral spring rigidly securedat one end tothe shaft and at the other end to the ear, as set forth.

2. In a blind or shutter operating device, the combination of thecrank-shaft E, the rotary lifter G, the shoulder or arm 1', and a meansfor connecting said shaft E with a vertical pintle secured to the blindG and adapted to transmit motion from the said shafttd the said pintleand through it to theblind, substantially as described.

3. In a blind or shutter operating device,

the combination of the crankshaft E, the r0 Y tary lifter G, theshoulder or arm I, and a means for connecting said shaft E with avertical pintle secured to the blind O and adaptrco ed to transmitmotion from the said shaft to the said pintle and through it to theblind, substantially as described.

4.- In combination with a blind or shutter pivoted by one of itsvertical edges, the crankshaft E, the revolving lifter G, the bracketK,- with the shoulders or arms iand Z, firmly secured to the pivotaledge of the blind or shutter, a flexible or universal joint connectingthe shaft E with the bracket K, the latch b,

and catch 01 or c, all arranged and adapted to 1 operate substantiallyas described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 23d day of N ovem-'
